Blood vessels that carry oxygen and nutrients from the heart to the rest of the body are called arteries. Arteries
that are not diseased are flexible and elastic. With increasing age and due to other factors, too much pressure in your arteries
can make the walls thick and stiff sometimes restricting blood flow to your organs and tissues. Hardening of arteries ensues which
is called as arteriosclerosis. Atherosclerosis is a specific type of arteriosclerosis, but the terms are sometimes used
interchangeably. The buildup of fats and cholesterol in and on walls of arteries (plaques) is called as atherosclerosis.
This process can restrict blood flow.
